Abstract

This study aims to see how the improvement of mathematical representation skills of class VIII students totaling 25 students at SMP Negeri 2 Sibolga in the 2022/2023 academic year after being subjected to learning that applies Van Hiele theory assisted by Geogebra. The type of research is Classroom Action Research with procedures that have repeated stages in Cycle I and Cycle II, namely problems, action planning, action implementation, observation, data analysis and reflection. The research began by finding that the average mathematical representation ability of students before the action was still in the low category, namely 48.8 with a percentage of 20% classical completeness, then the average ability increased to 70.67 (high) with 60% classical completeness in cycle I, and 87.25 (high) with 80% classical completeness in cycle II. The increase managed to go higher, seen from the increase in the gain index value which in cycle I was 0.39 (low) to 0.75 (high). In Indicator 1, the representation ability increased from 44 (low) to 63 (medium) then to 81.5 (high). Indicator 2 ability increased from 46 (low) to 67.66 (medium) then to 88.25 (high). In Indicator 3, the ability increased from 54 (medium) to 78.5 (high). In addition, the ability of the teacher/researcher in processing classroom activities increased significantly which in cycle I was 2.32 with a sufficient category to 3.03 with a good category. Then, the percentage of student activity also increased from 61.1% with a sufficient category to 82.4% with a high category. Through the results of this study, it can be concluded that the application of Van Hiele Theory with Geogebra assistance can improve the Mathematical Representation skills of 8th grade students of SMP Negeri 2 Sibolga in the 2022/2023 academic year.

Abstract

This research aims to determine the influence of Discovery Learning assisted by Geogebra Software on the learning motivation of eighth-grade students at SMP Negeri 6 Medan. This is a quantitative study with the posttest-only control group design for student motivation data and a pretest-posttest control group design for supporting data in the form of learning outcomes. The research subjects are Class VIII A with 31 students as the experimental group and Class VIII B with 31 students as the control group. Data collection techniques in this study were conducted using questionnaires and tests. Learning motivation and mathematics learning outcomes data were analyzed using descriptive and inferential analysis. Through t-test on the learning motivation data, a significance value of 0.000 < 0.05 was obtained, and the t-value > t-table, which is 4.355 > 2.042. Therefore, H0 is rejected, and Ha is accepted, which means there is an influence between the independent variable and the dependent variable. The positive t-value indicates a positive and direct influence. It can be concluded that Discovery Learning assisted by Geogebra Software has a positive effect on improving students' learning motivation in Class VIII at SMP Negeri 6 Medan, with an average learning motivation score of 76, classified as high. In contrast, the average score in the control class is 67.16.
